Tell us what’s happening:

What am I doing wrong here? Didn’t I made what it asked for?

Your code so far

def verify_card_number(card_number):
    sum_of_odd_digits = 0
    card_number_reversed = card_number[::-1]
    odd_digits = card_number_reversed[::2]

    for digit in odd_digits:
        sum_of_odd_digits += int(digit)


# User Editable Region

    sum_of_even_digits = 0
    even_digits = card_number_reversed[1::2]
    for digit in even_digits:
        number = int(digit) * 2
         if number >= 10:  
            print(number)

# User Editable Region

def main():
    card_number = '4111-1111-4555-1142'
    card_translation = str.maketrans({'-': '', ' ': ''})
    translated_card_number = card_number.translate(card_translation)

    verify_card_number(translated_card_number)

main()

Hi there! Your code is good, but there’s an extra space before if. Remove it so it lines up the same as number, but keep the indentation for print and others as they are. :blush:
